I'm going through some old nimblegen tiling array gff files and they have 2 types of lines. The first show a single position on the genome (;chr10P112111577;1) and the second show a range (CHR11:11425301-12332192;CHR1100P011570469;1). I understand the second type, but what is the first?? I looked at the ndf file and it doesn't explain it.

In the first example, the name can't be reporting a single position. It's more likely the specific probe ID. The number might represent the count; compare it to a recent set of GFF3 output I have:
